“I wish to supplement the warranted assertion that our experience of non-human nature is largely constructed by human culture, with an acknowledgement that human culture is itself structured and informed, in diverse ways, by the wider-than-human matrix of powers in which it is embedded. While our notions of the world may be structured by our particular culture, cultures are themselves structured by the interplay of gravity, winds, waters, and sunlight, by the migratory movements of various animals and the nutritional and medicinal powers of particular plants. Human culture, that is, is itself influenced, organized and mediated by many agencies that are not human or of human artifice.”
